No-twist entanglement of filament and apparatus therefor

摘要: A bundle of untangled filaments is passed through a confining passageway in which it subjected to number air jets entangle the yarn. Preferably, there are four jets, three on one side yarn and fourth opposite side. Usually two directed perpendicularly path at an angle spread yarn, single jet against bundle, slightly offset from where contact it. These impart twist factor about axis thereby some entanglement The countercurrently flow further separates entangles
